METAL PUNGHING MACHINE.

PATENT @rmex DENMARK, ASSIGNOR TO THE METAL-PUNCl-HNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 309,432, dated December 16, 1884.

Application li'ed April 1884i (Nomodcl l T0 aZZ whom "it-may concern:

Be it known that I, ANDEns ANDERSEN, a subject of the King of Denmark, residing at Copenhagen, Kingdom of Denmark, have invented certain new and useful Improvements in llfetal-Punching Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification, and in which Figure 1 is a side view of my improved machine for punching metal. Fig. 2 is a vertical sectional View of the anvil; and Figs. 3, at, and 5 arerespectively a top, a side, and a cross-sectional view of a slight modification ot' the worlcsupporting table.

Similar letters of reference indicate corresponding parts in all the iigures.

My invention has relation to machines for punching metal, and more particularly to machines for punching or clczining out the nailholes in horseshoes; and it consists in the improved construction and combination of parts hi the same, as hereinafter more fully described and claimed.

in the accompanying drawings, the letter A indicates the frame of the machine, which consists of a foot, 13, a table, 0, and upright sliding ays 1), in which the punch-carrying block 19 is reciprocated, 1* indicating the punch, and G indicating two arms projecting adjustably from the lower ends of the sliding ways upon both sides of the punch, serving to strip the work off the punch as it ascends, oiily one of which arms is shown in the drawings, and the punch is shown in dotted lines behind the exposed arm. A screw, 11', having a conical head, turns in the inner side of the frame above the table and below the ways, serving 1 to bear against the inner side of the work for the purpose of adjusting it, and the work rests upon an anvil, l, secured upon the table, having its upper side inclined outward, and having a block, J, laid into its upper side, having a mortise, 1i, registering with the punch, the

sides of which mortise diverge toward itslowcr end, as plainly shown in Fig. 2, and open into a channel, L, passing through the anvil for the purpose of carryingv off all particles of metal punched out of the work. Two arms, M, are pivoted at their inner ends upon the sides of the an vil, having their upper surfaces flush with the surface of the same, and are g connected by means of a bolt, N, to the middle of which the upper end of a bar, 0, is pivoted, the lower end ot'wli i ch bar is pivoted to the forward end of a lever, 1, pivoted under the table, having a set-screw, Q, at its inner end, by means of which the throw of the lever may be adjusted. the end of the screw bearing against of the lever is tilted upward, and a connectingrod, 1%, is pivoted at its upper end to the inner end of the lever and at its lower end to the outer arm of a footlcver or treadle, S, pivoted at the lower end of the foot of the frame, having a weight, T, upon its inner arm, and having a setscrew, U, passing through the outer arm of the treadle immediately outside the pivotal point of the eoniiectingroiil, the lower end of the said screw bearing against the footplate ot' the frame, and thus regulating the downward throw of the outer arm of the treadle.

- it will now be 'seen that by depressing the outer arm of the treadle, as shown in the drawings, the outer ends of the arms upon the on the upper sides of the said arms will be presented, lying flat below the punch, while when the outer arm of the treadle is released i the weight will tilt the lovers and connecting rods and arms in such a manner thatthe Work 1 supporting arms will be in an inclined position, ilush with the surface of the anvil, the T angle of their upper surfaces being shown by a I dotted. line in Fig. 11, thus presenting the work l'in an inclined position to the punch, and consequently causing an inclined perforation to f be made. I t will be seen that this construe l tioii will only admit of the work being pre sented at two difterent angles to the punch, and for the purpose of presenting the work at 1 any desired angleto the punch 1 construct the anvil with a recess, 'V, in which the arm Y may rock, the said arm having semi-cylindrical trunnions X upon its sides, which rock in semicylindrical. bearings Y in the upper side of the anvil, upon each side of the recess in the same, the upper flat sides of the trunnions 1 being flush with the upper side of the arm,

. the under side of the table when the inner end anvil will be raised, and the work resting upand the said arm has the punch-receiving mortise and its block in a line with the trunnions. The recess in the anvil has two segmental slots, Z, in its sides, extending through the sides of the anvil, and transverse pins A, passing through the arm below the mortise, slide in the said segment, securing the arm in its bearings and limiting its motion. Two laterally-projecting tables, B, are secured to the sides of the arm,.flush with its uppersurface, having slots 0, through which the upper sides of the anvil project, the said tables serving to make a larger bearing-surface for the work. The outer arm of the lever forms a handle, D, and a bolt, E, slides upon the side of the arm, havingaconnecting-rod, F, hinged to its outer end, which again is hinged to the short arm of a bell-crank, G, pivoted upon theside of the -handle, and bearing with its long arm againsta spring. H, and the inner end of the said sliding bolt engages a notched segment, I, secured to and projecting upward from the table of the frame, the bolt serving to adjust the arm, and with it the work, at any desired angle, enabling the machine to punch or clear out holes at any desired angle to the surface of the work.

, Having thus described my invention, I claim and desire to secure by Letters Patent of the I United States- 1. The combination, with a reciprocating punch, of a rigid anvil or support, a worksnpporting arm or arms pivoted upon the anvil, and means for tilting the said supporting arm or arms, as and for the purpose shown and set forth.

2. The combination, with a reciprocating punch, of a rigid anvil having a vertical recess in its middle, and formed with bearings in its upper face at both sides of the recess, a work nions rocking in the bearings, and having a mortise registering With the punch, and having downward]y;diverging sides, and means for adjusting the said arm at different angles, as

and for the purpose shown and set forth.

4. The combination, with a reciprocating punch, of arigid anvil having avertical recess in its middle, and formed with hearings in its upper face at both sides of the recess, a work supporting arm having trunnions rocking in the said bearings, and having a mortise registering with the punch, aspring-actuated bolt sliding in bearings upon the side of the worksupporting arm, and an upright segmental rack engaged by the end of the sliding bolt, as and for the purpose shown and set forth.

5. The combination of a reciprocating punch with a rigid anvilhaving-a vertical recess in its middle, and formed with semi-cylindrical bearings in its upper face at both sides of the recess, and with segmental slots in the lower portions of its sides, a work-supporting arm having laterally-projecting semi-eylindrical trunnions flush with its surface, rockin g in the bearings, havinglaterally-proj ectin g pins sliding in the segmental slots, and provided with a mortise registering with the punch, and means for adjusting the angle of So the arm, as and for the purpose shown and set forth.

6. The combination, with the reciprocating punch, of a rigid anvil having a vertical recess in its middle, and formed with semi-cylindrical bearings in its upper face at bot-h sides of the recess, and with segmental slots in the lower portions of the same, a work-supporting arm having laterally-projecting semicylindrical trunnions flush with its surface, 0

rocking in the bearings, and having a mortise registering with the punch, laterally-projecting pins projecting from the sides of the arm, sliding in the segmental slots, a spring-bolt sliding in bearings upon the side of the worksupporting arm, and an upright notched segment engaged by the said bolt, as and for the purpose shown and set forth. In testimony whereofI atlix my signature in presence of two witnesses.
